Added you as admin. To be clear, we're not using the repo to host binary files. However we can commit readme, manifests, storyboards and other versionable content. When we make a release, that is the moment we can upload the final release to the release page.

Github has specific reservations on repo sizes. A company I worked with bumped into the 1GB limit a few times. Actions were usually an email and a harsh warning that they'd freeze our repo when we got close to 1.5GB.
